Plants of perennial ryegrass, Lolium perenne L., infected with an endophytic fungus, Acremonium loliae Latch et al. were toxic to house crickets, Acheta domesticus L. Death followed progressive inactivity, culminating in 100% cricket mortality by 84 h. The epithelial lining of the crop and proventriculus of affected crickets was progressively loosened and detached, resulting in complete failure of the alimentary process. Besides the house cricket which is an acridid, antibiosis of a number of coleopterous and lepidopterous pests on endophyte-infected ryegrasses has been previously reported. Thus, the endophyte is an important source of insect resistance which plant breeders can incorporate into new crop varieties.
